Provided is a microneedle device which protects microneedle, has an easily portable shape, is free from such problems as breakage of small needles in the step of puncturing the skin with the microneedle, and ensures appropriate skin puncture for administering a drug. By studying the relationship between a device to be pressed to the skin and the height of an elevation on the skin surface under the pressing and thus producing a device equipped with microneedle that are embedded in a concave part having a definite depth, the microneedle can be surely and easily inserted and punctured into the skin while avoiding such problems as breakage of the small needles of the microneedle. Thus, a microneedle patch formulation, which is easily portable and ensures convenient drug administration to the skin, can be produced.
